Product Description

The DL250-1 is the most powerful processor in the DL205 family. It fits into the first slot of a DL205 base (such as the D2-06B-1). It features expanded memory, built-in PID control loops, and two communication ports. This CPU is a direct enhancement of the older DL250, offering more memory and faster processing speeds for modern automation requirements.

Product Parameters

• Memory: 14.8k words total (7.6k words for Program, 7.2k words for Data).

• I/O Capacity: Supports up to 8,192 local I/O points (when using remote I/O) or up to 256 local physical I/O points.

• Communication Ports: * Port 1: 6-pin RS-232C (supports K-sequence protocol for programming/HMI).

  • Port 2: 15-pin RS-232C/RS-422/RS-485 (supports Modbus RTU Master/Slave, DirectNET, and Remote I/O).

• Processing Speed: 0.6 ms per 1k Boolean instructions.

• Programming Language: Ladder Logic and RLL (Relay Ladder Logic) PLUS (Stage Programming).

• Instruction Set: Over 200 instructions, including floating-point math and PID.

• Battery Backup: Built-in lithium battery to maintain program and data during power loss.

Product Advantages

• Advanced PID Control: Supports up to 16 PID loops with auto-tuning, making it suitable for process control applications like temperature or pressure regulation.

• Flexible Communication: Port 2 is highly versatile, allowing the PLC to act as a Modbus Master for driving VFDs or as a Slave to a SCADA system.

• Stage Programming: Supports “Stage” logic, which simplifies the programming of complex sequential operations by breaking them into manageable states.

• Real-Time Clock: Built-in clock/calendar for time-stamping events or scheduling tasks.

• Cost-Effectiveness: Provides features typically found in high-end PLCs (floating point, PID, multiple protocols) at a significantly lower price point.

Precautions for Use

• Battery Replacement: Monitor the “BATT” LED. When it turns red, replace the lithium battery within a few days to avoid losing the user program and retentive data.

• Firmware Compatibility: Ensure your DirectSOFT programming software is updated to a version that supports the DL250-1 hardware.

• Port Pinouts: Note that Port 1 and Port 2 have different physical connectors (RJ12 vs. DA-15). Ensure you use the correct cables (e.g., DV-1000C or D2-DSCBL) to avoid port damage.

• Electrostatic Discharge (ESD): Always touch a grounded metal surface before handling the CPU to prevent static electricity from damaging the internal microprocessor.

Product Applications

• Process Control: Temperature control in industrial ovens or chemical mixing where PID loops are required.

• Water and Wastewater: Remote telemetry units (RTUs) for pump stations using Modbus communication over radio or cellular modems.

• Material Handling: Complex conveyor systems requiring high-speed sorting and data tracking.

• Machine Tooling: Controlling multi-axis motion sequences in CNC-like specialized machinery.

• Energy Management: Monitoring power meters and controlling HVAC loads via RS-485 networks.
